Note: For each score type, only students with both pre- and posttest scores were included. Due to missing data, the numbers for each domain vary slightly; the n for structure and sentence fluency in the Writing Matters pretest is 192 and the n for the comparison group in the content pretest and stance and conventions posttest is 105.
